Short video of the preparations and launch
And.....we got a mission pamplet for this launch! (translation available on request)
Target orbit is 644 km altitude SSO at 98.0 degrees inclination.
Can you translate items 10 and 11 in the launch sequence? (at 717 and 803 s)
I have
T+2:33 Stage 1 MECO
T+2:34 Stage 1 sep
T+2:57 Fairing sep
T+4:42 Stage 2 MECO
T+4:52 Stage 2 VECO (vernier engine cutoff)
T+4:53 Stage 2 sep
T+11:43 Stage 3 (burn? or MECO?)
T+11:57 (717s) - possibly stage 3 shutdown?
T+13:23 (803s) - possibly main payload sep?
T+14:03 BY-02 sep.
The name 高分辨率多模综合成像卫星 parses out as Gao (High) Fen bian lu (resolution) duomo (Multimode) zonge (integrated) chengxiang
(imaging) weixing (satellite) per google translate. I am a bit surprised by the use of "gao fen bian lu" rather than just the
usual abbreviated "gao fen" - perhaps this means this satellite is not a Gaofen series satellite but just happens to have 'high resolution'
in the description.
T+11:43 Stage 3 (burn? or MECO?)
Definitely shutdown.
T+13:23 (803s) - possibly main payload sep?
Yes, with a shorter name Gaofen duomo weixing.

T+11:43 is 3rd stage shutdown
T+11:57 is “3rd stage terminal guidnace shutdown” - since the 3rd stage doesn’t have verniers I guess either the YF-40 engine has a low thrust mode or they are referring to using the RCS.
T+13:23 is indeed GF satellite separation.
The Chinese are calling this GFDM or Gaofen Duomo (see last screen capture).
